Pygmy Eagle

Hieraaetus weiskei

The Pygmy Eagle (Hieraaetus weiskei) is a diminutive yet powerful raptor endemic to the montane forests of New Guinea, earning its 'pygmy' moniker as one of the smallest true eagles in the world.

Habitat

This specialized raptor inhabits primary and secondary montane rainforests, primarily found at elevations ranging from 700 to 3,000 meters, preferring areas with tall emergent trees for nesting and perching.

Range

The Pygmy Eagle is entirely restricted to the island of New Guinea, encompassing both Indonesian Papua (Western New Guinea) and Papua New Guinea. Its distribution is patchy but widespread across the central mountain ranges and isolated mountain blocks. Key areas include the Snow Mountains (Pegunu...
